Saturday at the New York Comic Con brought news for the Avengers, Superman, Legendary Comics and … Disney’s Prep & Landing? Here’s a round-up of announcements from the show today.

• With a big, blockbuster Avengers movie scheduled for next May, Marvel announced a new ongoing series, Avengers Assemble, by writer Brian Michael Bendis and artist Mark Bagley. The book will launch next March and will feature most of the Avengers featured in the movie — Iron Man, Captain America, Black Widow, Hawkeye and the Hulk. The first arc will feature the villainous group the Zodiac.

• Marvel also announced that writer Rick Remender and artist Gabriel Hardman will take over Secret Avengers with issue #21.1, adding new members and pitting them against a new Masters of Evil.

• At the Cup O’ Joe panel today, Marvel also announced a Disney/Marvel crossover — Prep & Landing: Mansion: Impossible. It features the elves from the Disney television special who prepare homes for the arrival of Santa Claus every Christmas eve — only this time they’re trying to break into Avengers Mansion to get it ready for Santa. Written by director Kevin Deters and drawn by story artist Joe Mateo, the story will run in the back of the Marvel Adventures books as well as Avengers #19 in November.

Legendary Entertainment has premiered the poster and print ad for Holy Terror, the long-awaited graphic novel by Frank Miller.

The revenge tale, set for release in September, follows The Fixer, a “Dirty Hairy”-style hero who takes the fight to al Qaeda after his city is target by terrorists. Initially, and famously, conceived as a Batman story, Holy Terror is described as “a no-holds-barred action thriller told in Miller’s trademark high-contrast, black-and-white visual style, which seizes the political zeitgeist by the throat and doesn’t let go until the last page.”

Three down, one to go … here’s a list of the major comics-related announcements made at Comic-Con International in San Diego on Saturday:

• A number of new projects were announced or promoted at Image’s Creator-Owned Comics panel, not the least of which is the return of Brian K. Vaughan to comic books. Vaughan will write a book called Saga, which is co-created and drawn by Fiona Staples. Vaughan told CBR that the book is “an epic drama chronicling the life and times of one young family fighting to survive a never-ending war. 100 percent creator-owned. Ongoing. Monthly. Fiona and I are banking issues now.”

• Image also announced that Walking Dead creator Robert Kirkman is collaborating with Charlie Adlard on a new series of graphic novels called Album. The books will be released roughly 18 months apart, 60 pages long, with different themes each year, with the first being Passenger. It’s co-published with Delcourt in France and will be available simultaneously in English and France.

• Jonathan Hickman and Nicky Pitarra will team up forThe Manhattan Projects at Image. Hickman is also doing a book called Secret with artist Ryan Godenheim.

Legendary Comics announced at its panel this afternoon at Comic-Con International that it will publish new projects from Paul Pope and Matt Wagner.

Set for release this holiday season, PulpHope is a more than 200-page retrospective of Pope’s career, featuring many pieces that haven’t been seen before. A previous edition was published in 2007 by AdHouse Books.

The Tower Chronicles, developed by Wagner with Legendary CEO Thomas Tull, is a supernatural action-adventure about a bounty hunter with a hidden past who, backed by a team of high-tech mercenaries, protects civilians from the things that go bump in the night.

“We are thrilled to be working with Pope and Wagner on these upcoming projects for Legendary Comics,” Editor-in-Chief Bob Schreck said in a statement. “Just as our film division works with the best-in-class talent and filmmakers to produce content for the fandom demographic, so too will Legendary Comics move forward on our mandate to publish works from the best in A the industry.”

Update: The Hollywood Reporter reports that Simon Bisley will provide artwork for the Tower Chronicles. They also provide additional details on the PulpHope book, calling it “a revamped version of the artist’s out-of-print art book titled PulpHope, stripping away 100 pages and throwing in 100 new ones incorporating work Pope has done in the music, toy and clothing spheres, as well as other material.”

Legendary Comics, the comic-publishing arm of Legendary Pictures, has revealed a new trailer for Frank Miller’s upcoming graphic novel Holy Terror. The project began as a “Batman vs. al-Qaeda” book for DC Comics before Miller eliminated Batman from it in favor of a new character called The Fixer, who you can see in action in the trailer.

The book will be published this September to coincide with the 10th anniversary of the 9/11 terrorist attacks.

The trailer was revealed by Legendary as the “first of four locks” being opened, and they ask fans to help open additional locks by sharing content on Facebook and Twitter. “This was the first of four locks that will reveal exclusive content throughout the weekend, so be sure to check back regularly. Remember, the more you spread the word, the faster each reveal will be released!”

Rich Johnston and Heidi MacDonald are both reporting that Frank Miller’s long-awaited graphic novel Holy Terror will be published this September, the tenth anniversary of the 9/11 terror attacks to which the book is a response. The project began as a “Batman vs. al-Qaeda” book for DC before Miller, feeling he’d taken the story too far outside of the Batman comfort zone, rejiggered it with an original hero called the Fixer and took it elsewhere. That elsewhere turns out to be Legendary Comics (the publishing subsidiary of the Legendary Pictures film shingle), helmed by former Oni/DC/IDW editor Bob Schreck. This oughta be a pip.
